Given the limitations of existing models for the nonlinear density field and its tracers, a lofty goal is then to produce an interpretable, analytic model that is accurate across all scales of cosmological interest.
Toward this goal we build upon the hybrid PT-halo model approach put forward by [1]} (MS14) and [2]} (SV15) for modeling dark matter two-point correlators - Halo-Zeldovich Perturbation Theory (HZPT).
There have been several other efforts in this hybrid-modeling direction for dark matter only correlators [3]}, [4]}, [5]}, [6]}.
However, both HZPT in its original incarnation and these previous works do not account for baryonic effects on the matter two-point correlators or the more observationally-relevant modeling of general tracer two-point correlators.
We address these shortcomings in this paper.
